Can someone explain how a whistler gauge works? I have Googled it and can't find them. Anyone happen to have a link to a picture of one? I can't even find them listed for sale anywhere, not sure what I am doing wrong with the search. Any help would be appreciated.

With it you are able to accurately measure the air displaced by a particular cylinder at a known temperature. The ci of air is multiplied by the number of cylinders giving the approx displacement of the motor. They will always read low. However a fair to decent tech will be able to distinguish between 305, 327, 355, 377, 383, 406, and larger displacements. If your motor "pumps" say 369 cubes, be prepared to pull a head for a bore and stroke check if you have a 358ci rule.
